VENTILATING HOOD FOB RANGES, ETC.

Application led January The present invention relates to an improved apparatus for gatherin and disposing of the fumes and odor la en air found in kitchens and particularly over the range .6 or stove used in cooking. Hoods' have been commonly used in kitchens placed directly over the range, and have been intended to carry away the fumes arising during the operation ofv cooking. These, however, are

only partl successful, both because some of the direct y rising vapors and fumes fail to enter the hood and because such odors as spread laterally find their way through the kitchen and neighboring apartments and are not disposed of. The present invention has been found to remedy these diiiiculties, making it possible to remove all odors and fumes that may tend to spread through the kitchen and neighboring apartments.

The invention is illustrated in a preferred embodiment by way of example in the accompanying drawings, wherein Figure 1 is a view in end elevation of a range with my improved hood over the same, Figure 2 is a view in verticalsection on the line 2--2 of Figure 3, Figure 3 is a view of the improved hood 1n front elevation with a part of the outer easin removed, and Fi re 4 is a plan view of t e same with a portion of' the top removed.

My improvement comprises an outer rectangular box-like outer casing or shell 10, closed at the ends and front and back, and supported over the range 11. It is pre- 85 ferred to place this directly against the kitchen ceiling, but it may have a lower position, in which case a top enclosing wall will be provided as shown at 12.

The front wallis provided with a num- 40 ber of openings 13, preferably provided with shutters, which open into the space over a horizontal partition 14 within the casing 10. This partition extends from the left hand wall of the casing 10. in Figure 3, partly along the same, and all the way from front 'to back of said casing, as shown in Figure 2.

Some distance beneath the partition 14 is placed a hood proper having a top wall 15 extending from the right hand wall in Figure 3 almost to the left hand wall, and having exit openings 16.' This top extends from the back (shown at the right in Figure 2) nearly to the front of the outer. casing 10, and'from this top plate, at ends and front there depend the flaring walls 17 and 8, 1926. Serial No. 80,095.

18 to alevel a little above the open bottom of the casing 10.

At the right hand end of the casing 10, and prefera ly at the back, is a separate enclosure 19 havln a door 20, wherein stands the motor 21, w lch drives the centrifugal blower 22. This blower is preferably located within a separate enclosure between the v walls 23 and 24, the former of which has an inlet openmg 25, so placed that it extends vertically above and below the edge of the partltion 14, as shown in' Figure 3. This blower 1s arranged to discharge into an exit lue 26, which may be led away in any convement direction.

It is to be understood that, while I have described the motor 21 located at the ri ht hand end of the main casing, and the ot er parts correspondingly placed, the reverse arrangement is, of course, within the invention.

The operation of the device, indicated by the arrows suggesting the direction of air currents, is as follows:

The fumes arising from the range 11 find their wall naturally into the hood 15, 17, 18, and are drawn thence through the openings 16 1nto the fan 22, being driven out through the iue 26. Some of these fumes inevitably tend to escape from the edges of the hood, as has been commonly experienced hitherto. These escaping fumes, in my improvement, are caught by the fan suction operating in the passages between the edges of the hood and the main casing as shown in Figure 3, and are drawn into the fan 22, as shown in that fi ure. At t e same time any fumes or odors that may temporarily escape laterally into the kitchen are drawn through the openings 13, and travel over the partltion 14, being also driven out by the fan.

The invention may be embodied in a. variety of modified forms, and I do not limit myself to the details herein shown and described.

What I claim is 1. Means for the purpose described comprising an outer casing supported over a kitchen range, a hood proper within said casing and spaced therefrom, having an exit opening, a discharge iiue, and a motorblower above said hood adapted to blow air into said flue, said outer casing having openings above the hood for admittin air from the front of the outer casing to t e blower.

2. Means for the p urpose described comsaid flue; said'outer casing having openings prising an outer casmg supported over a in its front above said partltion.

kitchen range, a hood` pro er within said casing, spaced therefrom, avin an yexit 5 opening, a horizontal partition divlding said space into two passages, a discharge Hue, and a motor-blower, adapted to blow air into In testimony whereof I have hereto axed 10 rlny slgnature on this 6th day of January THEODORE R. N. GERDES.
